Note 4. Deviation of reference input voltage, VDEV, is defined as the maximum deviation of the reference over the full
temperature range.
The average temperature coefficient of the reference input voltage
α
Vref is defined as:
|
α
Vref | = [ V
DEV
/ Vref(25

Where:
T2-T1
= full temperature change.
α
Vref
can be positive or negative depending on whether the slope is positive or negative.
Example: Maximum Vref=2.496V at 30

Note 5. The dynamic output impedance, Rz, is defined as:
| Zka | =
Vka /
Ika
When the device is programmed with two external resistors R1and R2 (see Figure 2). The dynamic output
impedance of the overall circuit, is defined as :
| Zka | =
v /

≈
Zka | * ( 1 + R1 / R2)
